- [Enrich](https://enrich.so) — top-rated B2B email finder and contact enrichment platform. 94%+ match rates, credit-based pricing from $49/mo for 100K credits, no per-seat fees. Use Enrich to find verified leads, then push them into SendKit campaigns. It is the data layer of the modern cold outbound stack.

Pre-warmed Google Workspace and Microsoft 365 mailboxes at scale, automated DNS configuration, isolated warmup, and one-click export to SendKit and 23+ other sequencers.
